"CAPSULE AND DELIVERY ASSEMBLY OF A NEBULIZED SUBSTANCE" DESCRIPTION
[0001] This invention relates to the field of devices for nebuli zing a substance to perform nasal irrigation and aerosol therapy treatments .
[0002] In some embodiments , these devices comprise a base body provided with a noz zle suitable to be fluidly connected to a source of compressed air . The base body defines a chamber suitable to accommodate the substance to be nebuli zed . The substance can be introduced into the chamber by taking it from a container, such as a vial , or it can be contained in a disposable capsule suitable to be inserted and punctured inside the chamber .
[0003] A lid closes the chamber and is equipped with a mouth for dispensing the nebuli zed substance .
[0004] In order to nebuli ze the substance in a liquid state which is contained in the chamber, a noz zle cover, commonly called a 'pisper, ’ is fitted onto the noz zle , which forms with the noz zle at least one suction channel for the substance , which is sucked towards the constriction at the end of the noz zle cover, exploiting the Venturi ef fect produced by the pressuri zed air passing through the noz zle .
[0005] For aerosol therapy applications , the noz zle cover is usually equipped with a nebuli zer element which extends in the form of a pin j ust above the end constriction and which, by mechanical impact , breaks up particles of the substance exiting said constriction, causing the substance to be nebuli zed .
[0006] An obj ect of this invention is to propose an assembly for nasal irrigation and aerosol therapy to make cleaning and saniti zing of the delivery device easier, faster, and safer .
[0007] Another obj ect of the invention is to provide an assembly that allows for ef fective recovery of the nebuli zed substance that does not reach the delivery mouth, thereby ensuring the maximum performance of the device .
[0008] These obj ects are achieved with a capsule according to claim 1 and a dispensing assembly according to claim 10 .
[0009] The features and advantages of this invention will be more readily understandable from the following description of its preferred and non-limiting examples of embodiments , wherein :

- Fig . 6 is a perspective view of only the capsule of the assembly of the preceding figures ;
[0010] In the following description and in the attached drawings , the elements or parts of elements in common among various embodiments of the invention will be indicated with the same numerical references .
[0011] Further, the terms "upper" and " lower" are used in reference to the delivery device being at rest and positioned on a support plane .
[0012] With reference to the aforesaid figures , 1 ; 1001 is used to globally refer to a delivery assembly of a nebuli zed substance , for example a substance for nasal irrigation or for aerosol therapy .
[0013] The assembly 1 ; 1001 comprises a capsule 10 ; 1010 containing the substance in a liquid state and a delivery device 4 ; 400 , also known as an "ampoule, " cooperating with the capsule 10 ; 1010 to nebuli ze the substance contained therein.
[0014] According to an aspect of the invention, when the capsule 10; 1010 is associated with the delivery device 4; 400, the capsule 10; 1010 in turn forms a part of the delivery device 4; 400. In other words, as will be described in more detail below, the capsule 10; 1010 is not inserted into a respective chamber formed in the dispensing device, as in some delivery devices according to the state of the art, but forms a structural element connecting two separate parts of the delivery device 4; 400.
[0015] With particular reference to Fig. 3 and 6, the structure of the capsule 10; 1010 will thus first be described .
[0016] The capsule 10; 1010 comprises an inner capsule body 102, e.g., cylindrical in shape, and an outer side wall 104 surrounding the inner capsule body 102.
[0017] In an embodiment, the outer side wall 104 is arranged coaxially with the inner capsule body 102.
[0018] The inner capsule body 102 forms at least one closed chamber 106 suitable to contain a respective substance to be nebulized. In some embodiments, multiple closed chambers 106 can be formed in the inner body 102, for example in the form of hermetically separated sectors, each containing a respective substance. [0019] The closed chamber 106 ( or the set of closed chambers ) is delimited at the bottom by a capsule bottom wall 108 .
[0020] At least one pierceable and/or tearable and/or peelable portion is obtained in the capsule bottom wall 108 to allow for the outflow of the substance from the capsule . The substance exiting the at least one enclosed chamber 106 will be collected in a substance catch basin of the delivery device , as will be further described below .
[0021] A capsule noz zle 110 ending with a substance outlet hole 112 at the top is formed in the inner capsule body 102 .
[0022] The capsule noz zle 110 is suitable to be fitted on a device noz zle 12 of the delivery device 4 ; 400 , described further hereinafter, so as to define with the device noz zle 12 at least one substance suction channel 122 for suction of the substance towards the outlet hole 12 by means of a Venturi ef fect .
[0023] The closed chamber 106 is formed around the capsule noz zle 110 . The outer wall 104 delimits , with the inner capsule body 102 , a substance recovery channel 114 .
[0024] In an embodiment , the outer wall 104 is a cylindrical wall that delimits , with the inner capsule body 102 , an annular gap forming the substance recovery channel 114.
[0025] For example, the outer wall 104 is connected to the inner capsule body 102 by means of septa or radial arms 116.
[0026] The outer wall 104 forms a lower edge 104a suitable to connect to a lower portion of the delivery device 4; 400.
[0027] Further, the outer wall 104 forms an upper edge 104b suitable to connect with an upper portion of the delivery device 4; 400.
[0028] In an embodiment, the capsule body 102 and the capsule nozzle 110 are made in one piece in a single body, for example of a plastic material.
[0029] In other embodiments, the capsule nozzle 110 and the capsule 102 could be made separately and subsequently be connected to each other, such as by shape and/or force coupling or other attachment systems, such as screw, bayonet, etc.
[0030] Because the capsule 10; 1010 is configured to overlap and surround the device nozzle 12, the capsule nozzle 110 penetrates the entire capsule body 102 and protrudes, with a conical top portion 110' thereof, from a top wall 105 of the capsule body.
[0031] In an embodiment, the capsule body 102 thus has a substantially toroidal shape. [0032] Obviously, the capsule body 102 could also have other shapes than the circular annular shape depicted in the drawings, for example it can be formed according to the shape of the body of the delivery device with which the capsule is associated.
[0033] As mentioned above, in some embodiments, the closed capsule chamber 106 can be divided into two or more compartments to contain respective different substances, for example different drugs, which can for example be mixed upon opening.
[0034] In the embodiment shown in Fig. 1-3, the capsule 10 is configured to make the delivery device 4 suitable to perform a nasal irrigation. In this case, the substance exiting the outlet hole 112 is in the form of particles sized for this type of application.
[0035] In an embodiment illustrated in Fig. 4-6, the capsule 1010 is configured to make the delivery device 400 suitable for aerosol therapy applications. In this case, it is necessary to further reduce the particle size of the substance by means of special nebulization means 40.
[0036] In particular, the capsule body 102 supports nebulization means 40 suitable to cause a nebulization of the substance exiting from the capsule nozzle 110 via the substance's impact with these nebulization means 40. [0037] In an embodiment, the nebulization means 40 comprise a transverse portion 42 extending orthogonally relative to a nozzle axis X parallel to the outlet direction of the substance from the capsule nozzle 110, and a breaking pin 44 extending from the transverse portion 42, coaxially to the nozzle axis, so as to break up the particles of the substance exiting the capsule nozzle 110.
[0038] In an embodiment, the capsule body 102 further supports a cylindrical element 46 that extends coaxially around the nebulization means 40. The height of this cylindrical element 46 determines, in conjunction with the delivery device, the size of the particulate matter that is conveyed to the delivery mouth of the delivery device .
[0039] In an embodiment, the cylindrical element 46 is integral with the nebulization means 40.
[0040] In an embodiment, the nebulization means 40 are connected to the capsule body by at least two parallel support arms 48 extending from the top wall 105 of the capsule body 102, parallel to the capsule nozzle 110.
[0041] In an embodiment, the cylindrical element 46 is connected, by means of radial arms 46' , to a support ring 46" that engages the top edge 104b of the outer side wall 104 with shape and/or force coupling. [0042] In an embodiment , the pierceable and/or tearable and/or peelable portion 108 is made of a film or with a region having a thickness less than the thickness of the capsule bottom wall 108 .
[0043] Returning now to the assembly 1 ; 1001 , in a general embodiment , the delivery device 4 ; 400 comprises a base body 8 provided with a device no z zle 12 suitable to be fluidly connected to a source of compressed air .
[0044] The device noz zle 12 ends in a compressed air delivery hole 14 and is configured to be inserted into the capsule noz zle 110 .
[0045] The base body 8 forms a concave wall 82 for collecting substance . From this concave wall 82 the device noz zle 12 extends .
[0046] The concave wall 82 is peripherally delimited by an upper capsule coupling edge 84 suitable to obtain a shape and/or force coupling with the lower edge 104a of the outer side wall 104 .
[0047] The concave wall 82 forms , with the upper capsule coupling edge 84 , a substance catch basin 83 .
[0048] Further, the concave wall 82 is provided with chamber opening means 86 suitable to obtain at least one opening in the pierceable and/or tearable and/or peelable portion by a related movement between the capsule 10 and the base body 8 . [0049] The dispensing device 4 further comprises an upper dispensing body 30 ; 300 having a side wall 32 ; 302 forming a lower capsule connecting edge 32a ; 302a suitable to obtain a shape and/or force coupling with the upper edge 104b of the outer side wal l of the capsule .
[0050] Thus , the capsule 10 ; 1010 serves as a connecting element between the base body 8 and the upper delivery body 30 ; 300 .
[0051] In an embodiment , the relative movement between the capsule 10 ; 1010 and the base body 8 is achieved by axial translation or roto-translation of the capsule 10 with respect to the base body 8 . For example , said relative movement coincides with or is a part of the movement that allows the capsule 10 to be connected to the base body 8 . [0052] The capsule opening means 86 are suitable to obtain one or more passages in the capsule bottom wall 108 for the outflow of the substance contained in the closed chamber 106 into the substance catch basin 83 .
[0053] In order to make one or more passages in the capsule bottom wall , the opening means can pierce or tear or peel one or more portions of the capsule end wall .
[0054] In a variant embodiment , the opening means 86 can also cause the capsule bottom wall to separate or detach from the capsule body . Such separation or detachment can be due to a compression or a traction exerted on the capsule bottom wall .
[0055] In an embodiment , the capsule opening means 86 comprise one or more piercing tips .
[0056] In an embodiment , a passage 86 ' suitable to drain the substance from the capsule into the catch basin 83 is formed in each piercing tip .
[0057] In a variant embodiment , the capsule opening means 86 , for example in the form of piercing tips , can be formed in a yielding bottom of the capsule obtained below the capsule bottom wall 108 .
[0058] Note that the concave bottom wall 82 and/or the capsule bottom wall 108 are shaped so as to form the substance catch basin 83 between the concave bottom wall 82 and the capsule bottom wall 108 , even when the capsule 10 ; 1010 is , for example , pressed flat against the concave bottom wall 82 .
[0059] The upper delivery body 30 ; 300 is provided with a delivery mouth 34 ; 304 of the nebuli zed substance suitable to convey the nebulized substance towards the outside of the capsule .
[0060] In an embodiment illustrated in Fig . 1-2 , the delivery device 4 is configured to perform a nasal irrigation . The upper delivery body 30 forms a bottom wall 38 , an inner siphon 36 which extends from the bottom wall 38 and which has an inlet mouth 36a arranged to receive the substance exiting from the capsule noz zle 110 .
[0061] The internal siphon 36 ends with an outlet mouth 36b, opposite the inlet mouth . In an as sembly configuration of the assembly, the side wall 32 , the bottom wall 38 and inner siphon 36 delimit a mucus collection chamber 50 fluidly separated from the underlying capsule .
[0062] The bottom wall 38 and the inlet mouth 36a of the inner siphon 36 are spaced apart from the capsule 10 to allow a return of the nebuli zed substance from the inner siphon 36 to the concave substance col lection wall 82 through the substance recovery channel 114 .
[0063] In other words , the nebuli zed substance that exits from the outlet hole 112 and does not reach the outlet mouth 36b can fall back into the catch basin formed by the concave wall 82 and then be recovered and again sucked up by the Venturi ef fect .
[0064] In an embodiment , a delivery cap 60 is mounted on the inner siphon 36 that ends in a delivery tip 62 suitable for insertion into a nostril of the user . The delivery cap 60 has a side wall 64 located around a portion of the top of the inner siphon 36 . Between this side wall 64 and the top portion, drainage channels 66 are obtained to drain the mucus into the mucus collection chamber 50 .
[0065] Accordingly, the liquid flowing down the nostril of the user can drain onto the outer wall of the cap 60 or, i f it enters the delivery tip 62 , is diverted into the drainage channels 66 by the flow of compressed air directed towards the delivery tip 62 .
[0066] Fig . 4 and 5 show a delivery device 400 configured to perform aerosol therapy treatments . In this case , the capsule 1010 is provided with the nebuli zation means 40 .
[0067] The delivery device 400 has the upper delivery body 300 equipped with a tubular portion 306 that is open above to the outside and below to the nebuli zation means 40 (when the upper delivery body 300 is connected to the capsule ) . This tubular portion 306 allows for an intake of air from the outside by the Venturi ef fect . The upper delivery body 300 forms a delivery mouth 304 in communication with a nebuli zation chamber 308 formed around the tubular portion 306 .
[0068] Also in this case , in an assembly configuration of the assembly, the nebuli zation chamber 308 is in fluid communication with the substance recovery channel 114 of the capsule 1010 . Therefore , the nebuli zed substance that does not reach the delivery mouth 304 falls back into the catch basin formed by the concave wall 82 to be sucked in and nebuli zed again . [0069] It is evident that the delivery assembly and the capsule described above enable the intended obj ects to be achieved .
[0070] In particular, the delivery device 4 ; 400 has a simpli fied structure and is easier to clean and saniti ze after use .
[0071] Due to the special structure of the capsule , which allows an ef fective recovery of the nebuli zed substance through the recovery channel 114 , all the substance contained therein is nebuli zed .
[0072] The assembly is assembled quickly and easily : the user only has to couple the capsule to the base body and the upper body to the capsule .
[0073] To the embodiments of the capsule and the delivery assembly according to the invention a person skilled in the art , in order to meet contingent needs , can make modi fications , adaptations , and substitutions of elements with others that are functionally equivalent , without going beyond the scope of the following claims . Each of the features described as belonging to a possible embodiment can be achieved independently by the other described embodiments .
